I-7520 (RS-232 to RS-485, Isolation site RS-232) - RS-232 to RS-485 Converter with Din Rail Mount
The I-7520 is an RS-232 to RS-485 Converter with auto tuning function, auto switching baud rate, and is made of fire retardant materials. Most industrial computer systems provide standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, communication range, and networking capabilities. The RS-485 standard overcome these limitations by using differential voltage lines for data and control signals, which converts RS-232 signals into isolated RS-485 signals with no need to change any hardware or software.
